Getting content from custom fields of different pages on a single page

I want to get content from one custom field of different pages along side their page titles and I’m using the following code:

<?php
    $mypages = get_pages( array(
    'sort_order' => 'ASC',
    'sort_column' => 'post_title',
    'hierarchical' => 1,
    'exclude' => '',
    'include' => '',
    'meta_key' => '',
    'meta_value' => '',
    'authors' => '',
    'child_of' => 53,
    'parent' => -1,
    'exclude_tree' => '',
    'number' => '',
    'offset' => 0,
    'post_type' => 'page',
    'post_status' => 'publish'
 ) );

    foreach( $mypages as $page ) {      
        $content = $page->post_content;
                $new = $page->get_post_custom_values('new_file');
        if ( ! $content ) // Check for empty page
            continue;

        $content = apply_filters( 'the_content', $content );
    ?>
        <h2><a href="<?php echo get_page_link( $page->ID ); ?>"><?php echo $page->post_title; ?></a></h2>

                        <a style="display:block; text-align: center;" title="Download Now" href="<?php $new;  ?>"><img src="<?php bloginfo('template_url'); ?>/images/new-file.png" alt="Download the File" /></a>


    <?php
    }   
?>

I’m able to get page title but not getting my custom fields value. Please guide me in this regard. Your help’ll be highly appreciated in this regard.
